Plant-based diets, animal agriculture, and the connection with urological and planetary health.

PURPOSE OF REVIEW: We summarize the latest evidence regarding the impact of plant-based diets on urological and planetary health to facilitate patient counseling and research regarding dietary intervention. RECENT FINDINGS: Studies have highlighted the association of plant-based diets with a lower risk of multiple urological conditions including prostate cancer, erectile dysfunction, benign prostatic hyperplasia, and nephrolithiasis, as well as benefits for planetary health. SUMMARY: Plant-based diets are associated with numerous benefits that co-promote urological and planetary health.

Risk Factors and Contemporary Management Options for Pain and Discomfort Experienced During a Prostate Biopsy.

PURPOSE OF REVIEW: Prostate fusion biopsy, an innovative imaging modality for diagnosing prostate cancer, presents certain challenges for patients including discomfort and emotional distress, leading to nonadherence to treatment and follow-ups. To inform clinicians and offer pain relief alternatives to patients, this review delves into the risk factors for increased pain and modern management options to alleviate pain during prostate biopsy. RECENT FINDINGS: Individual responses to pain vary, and the overall experience of pain during a prostate biopsy has been contributed to numerous factors such as patient age, prostate volume, previous biopsy experience, and more. As a result, several strategies aim to mitigate pain during in-office procedures. Notably, techniques including pharmacological analgesics, hand holding, heating pads, entertainment/virtual reality, and distraction have shown significant efficacy. Existing studies explore risk factors influencing pain intensity during prostate biopsy and effective pain management strategies. This review consolidates available information to guide clinicians in enhancing patient comfort and thus, encourage surveillance adherence.

The effect of a fermented soy beverage among patients with localized prostate cancer prior to radical prostatectomy.

BACKGROUND: Fermented soy products have shown to possess inhibitory effects on prostate cancer (PCa). We evaluated the effect of a fermented soy beverage (Q-Can®), containing medium-chain triglycerides, ketones and soy isoflavones, among men with localized PCa prior to radical prostatectomy. METHODS: We conducted a placebo-controlled, double-blind randomized trial of Q-Can®. Stratified randomization (Cancer of the Prostate Risk Assessment (CAPRA) score at diagnosis) was used to assign patients to receive Q-Can® or placebo for 2-5 weeks before RP. Primary endpoint was change in serum PSA from baseline to end-of-study. We assessed changes in other clinical and pathologic endpoints. The primary ITT analysis compared PSA at end-of-study between randomization arms using repeated measures linear mixed model incorporating baseline CAPRA risk strata. RESULTS: We randomized 19 patients, 16 were eligible for analysis of the primary outcome. Mean age at enrollment was 61, 9(56.2%) were classified as low and intermediate risk, and 7(43.8%) high CAPRA risk. Among patients who received Q-Can®, mean PSA at baseline and end-of-study was 8.98(standard deviation, SD 4.07) and 8.02ng/mL(SD 3.99) compared with 8.66(SD 2.71) to 9.53ng/mL(SD 3.03), respectively, (Difference baseline - end-of-study, p = 0.36). There were no significant differences in Gleason score, clinical stage, surgical margin status, or CAPRA score between treatment arms (p > 0.05), and no significant differences between treatment arms in end-of-study or change in lipids, testosterone and FACT-P scores (p > 0.05). CONCLUSIONS: Short exposure to Q-Can® among patients with localized PCa was not associated with changes in PSA levels, PCa characteristics including grade and stage or serum testosterone. Due to early termination from inability to recruit, study power, was not achieved.

Adaptation of the socioecological model to address disparities in engagement of Black men in prostate cancer genetic testing.

BACKGROUND: Black men consistently have higher rates of prostate cancer (PCA)- related mortality. Advances in PCA treatment, screening, and hereditary cancer assessment center around germline testing (GT). Of concern is the significant under-engagement of Black males in PCA GT, limiting the benefit of precision therapy and tailored cancer screening despite longstanding awareness of these disparities. To address these critical disparities, the Socioecological Model (SEM) was employed to develop comprehensive recommendations to overcome barriers and implement equitable strategies to engage Black males in PCA GT. METHODS: Clinical/research experts, national organization leaders, and community stakeholders spanning multiple regions in US and Africa participated in developing a framework for equity in PCA GT grounded in the SEM. A novel mixed-methods approach was employed to generate key areas to be addressed and informed statements for consensus consideration utilizing the modified Delphi model. Statements achieving strong consensus (> =75% agreement) were included in final equity frameworks addressing clinical/community engagement and research engagement. RESULTS: All societal levels of the SEM (interpersonal, institutional, community, and policy/advocacy) must deliver information about PCA GT to Black males that address benefits/limitations, clinical impact, hereditary cancer implications, with acknowledgment of mistrust (mean scores [MS] 4.57-5.00). Interpersonal strategies for information delivery included engagement of family/friends/peers/Black role models to improve education/awareness and overcome mistrust (MS 4.65-5.00). Institutional strategies included diversifying clinical, research, and educational programs and integrating community liaisons into healthcare institutions (MS 4.57-5.00). Community strategies included partnerships with healthcare institutions and visibility of healthcare providers/researchers at community events (MS 4.65-4.91). Policy/advocacy included improving partnerships between advocacy and healthcare/community organizations while protecting patient benefits (MS 4.57-5.00). Media strategies were endorsed for the first time at every level (MS 4.56-5.00). CONCLUSION: The SEM-based equity frameworks proposed provide the first multidisciplinary strategies dedicated to increase engagement of Black males in PCA GT, which are critical to reduce disparities in PCA-mortality through informing tailored screening, targeted therapy, and cascade testing in families.

Survival outcomes of patients treated with local therapy for nonmetastatic prostate cancer with high prostate-specific antigen concentrations.

BACKGROUND: Patients with nonmetastatic prostate cancer (nmPCa) and high prostate-specific antigen (PSA) levels due to the high likelihood of metastasis pose a clinical dilemma regarding their optimal treatment and long-term outcomes after initial local therapy. We aimed to evaluate the oncologic outcomes of patients treated with radical prostatectomy (RP) or radiotherapy (RT) for nmPCa with high PSA levels. METHODS: We queried the Surveillance, Epidemiology, and End Results (SEER) database to identify patients diagnosed with nmPCa who received RP or RT from 2004 through 2015. We included nmPCa patients with high PSA levels categorized as ≥50 and ≥98 ng/mL, the highest level recorded in SEER. We used the Kaplan-Meier method and Cox proportional hazards to analyze cancer-specific (CSS) and overall survival (OS). RESULTS: We included 6177 patients with nmPCa and PSA ≥ 50 ng/mL at diagnosis; 1698 (27%) had PSA ≥ 98 ng/mL. Of these, 1658 (26.8%) underwent RP and 4519 (73.16%) patients received primary RT. Within a median of 113 months (interquartile range 74-150 months), the 5- and 10-year CSS estimates were 92.3% and 81.5% respectively; 10-year OS was 61%. In the PSA ≥ 98 ng/mL subgroup 5- and 10-year CSS estimates were 89.2% and 76%, respectively. In multivariable analyses for CSS, ISUP grade group (p < 0.001), N stage (p < 0.001), treatment with RP (hazard ratio [HR] = 0.60, 95% confidence interval [CI] 0.43-0.83, p < 0.001), and patient's age (p < 0.05) were associated with improved CSS. In the whole cohort of patients with PSA ≥ 50 ng/mL and RP subgroup, PSA failed to retain its independent prognostic value for CSS. CONCLUSIONS: Patients treated with local therapy for nmPCa with very high PSA at diagnosis have relatively good long-term oncological outcomes. Therefore, among well-selected patients with nmPCa, high PSA levels alone should not preclude the use of radical local therapy. Potential selection bias limits inferences about the relative effectiveness of specific local therapies in this setting.

Use of Monitoring Tests Among Patients With Localized Prostate Cancer Managed With Observation.

PURPOSE: It is unknown whether compliance with recommended monitoring tests during observation of localized prostate cancer has changed over time. MATERIALS AND METHODS: We performed a retrospective cohort study of Medicare beneficiaries diagnosed with low- or intermediate-risk prostate cancer in 2004-2016 who were initially managed with observation for a minimum of 12 months. The primary objective was to examine rates of PSA testing, prostate biopsy, and prostate MRI. We used multivariable mixed effects Poisson regression to determine whether rates of PSA testing and prostate biopsy increased over time. In addition, we identified clinical, sociodemographic, and provider factors associated with the frequency of monitoring tests during observation. RESULTS: We identified 10,639 patients diagnosed at a median age of 73 (IQR 69-77) years. The median follow-up time was 4.3 (IQR 2.7-6.6) years after diagnosis. Among patients managed without treatment for 5 years, 98% received at ≥1 PSA test, 48.0% ≥1 additional prostate biopsy, and 31.0% ≥1 prostate MRI. Among patients managed with observation for ≥12 months, mixed effects Poisson regression revealed that rates of PSA testing and biopsy increased over time (per calendar year: RR 1.02, 95% CI: 1.02-1.03 and RR 1.10, 95% CI: 1.08-1.11, respectively). Clinical and sociodemographic factors including age, clinical risk, race/ethnicity, census tract poverty, and region were associated with rates of biopsy and PSA testing. CONCLUSIONS: Use of recommended monitoring tests including repeat prostate biopsy remains low among Medicare beneficiaries undergoing observation for low- and intermediate-risk prostate cancer.

Personalizing approaches to the management of metastatic hormone sensitive prostate cancer: role of advanced imaging, genetics and therapeutics.

PURPOSE: To summarize contemporary and emerging strategies for the diagnosis and management of metastatic hormone sensitive prostate cancer (mHSPC), focusing on diagnostic testing and therapeutics. METHODS: Literature review using PUBMED-Medline databases as well as clinicaltrials.gov to include reported or ongoing clinical trials on treatment for mHSPC. We prioritized the findings from phase III randomized clinical trials, systematic reviews, meta-analyses and clinical practice guidelines. RESULTS: There have been significant changes to the diagnosis and staging evaluation of mHSPC with the integration of increasingly accurate positron emission tomography (PET) imaging tracers that exceed the performance of conventional computerized tomography (CT) and bone scan. Germline multigene testing is recommended for the evaluation of patients newly diagnosed with mHSPC given the prevalence of actionable alterations that may create candidacy for specific therapies. Although androgen deprivation therapy (ADT) remains the backbone of treatment for mHSPC, approaches to first-line treatment include the integration of multiple agents including androgen receptor synthesis inhibitors (ARSI; abiraterone) Androgen Receptor antagonists (enzalutamide, darolutamide, apalautamide), and docetaxel chemotherapy. The combination of ADT, ARSI, and docetaxel chemotherapy has recently been evaluated in a randomized trial and was associated with significantly improved overall survival including in patients with a high burden of disease. The role of local treatment to the prostate with radiation has been evaluated in randomized trials with additional studies underway evaluating the role of cytoreductive radical prostatectomy. CONCLUSION: The staging and initial management of patients with mHSPC has undergone significant advances in the last decade with advancements in the diagnosis, treatment and sequencing of therapies.

Local Therapeutics for the Treatment of Oligo Metastatic Prostate Cancer.

PURPOSE OF REVIEW: Metastatic prostate cancer remains universally lethal. Although de-novo metastatic prostate cancer was historically managed with systemic therapy alone, local therapies are increasingly utilized in the early treatment of the disease, particularly in patients with oligometastatic prostate cancer (OMPC). OMPC represents an intermediate stage between clinically localized and widespread metastatic disease. Diseases classified within this stage present an opportunity for localized targeting of the disease prior to progression to widespread metastases. The purpose of this review is to discuss the contemporary and emerging local therapies for the treatment of OMPC. RECENT FINDINGS: To date, there are three utilized forms of local therapy for OMPC: cryoablation, radiation therapy, and cytoreductive prostatectomy. Cryoablation can be utilized for the total ablation of the prostate and has shown promising results in patients with OMPC either in combination with ADT or with ADT and systemic chemotherapy. Radiation therapy along with ADT has demonstrated improvement in progression-free survival. The STAMPEDE Arm G, PEACE-1, and the HORRAD clinical trials have investigated radiation therapy for mPCa compared to standard of care versus systemic therapy with varying results. Cytoreductive radical prostatectomy (CRP) in conjunction with ADT has also been proposed in the management of OPMC with promising results from case-control and retrospective studies. Currently there are larger controlled trials investigating CRP for OPMC including the SIMCAP, LoMP, TRoMbone, SWOG 1802, IP2-ATLANTA, g-RAMPP, and FUSCC-OMPCa trials. Given the novel nature of local treatments for OPMC, treatment selection is still controversial and requires long-term follow-up and randomized clinical trials to aid patient and clinician decision making.

Prostate Cancer Screening and Incidence among Aging Persons Living with HIV.

PURPOSE: The risk of prostate cancer among persons living with human immunodeficiency virus (PWH) is not well understood and may be obscured by different opportunities for detection. MATERIALS AND METHODS: We identified 123,472 (37,819 PWH and 85,653 comparators) men enrolled in the Veterans Aging Cohort Study, a prospective national cohort of PWH and demographically matched, uninfected comparators in 2000-2015. We calculated rates of prostate specific antigen (PSA) testing by human immunodeficiency virus (HIV) status and fit multivariable Poisson models comparing the rates of PSA testing, prostate biopsy, and cancer incidence. RESULTS: The mean age at enrollment was 52 years. Rates of PSA testing were lower in PWH versus uninfected comparators (0.58 versus 0.63 tests per person-year). Adjusted rates of PSA screening and prostate biopsy were lower among PWH (incidence rate ratio [IRR] 0.87, 95% CI 0.75-0.84 and IRR 0.79 95% CI 0.74-0.83, respectively). The crude IRR for prostate cancer was lower in PWH versus controls (IRR 0.90, 95% CI 0.83-0.97). However, in a multivariable model adjusting for PSA testing, cancer incidence was similar by HIV status (IRR=0.93, 95% CI 0.86-1.01, p=0.08). Among patients who received a prostate biopsy, incidence of prostate cancer did not differ significantly by HIV status (IRR 1.06, 95% CI 0.98-1.15, p=0.15). Among incident cancers, there were significant differences in the distributions of Gleason grade (p=0.05), but not cancer stage (p=0.14) by HIV status. CONCLUSIONS: When accounting for less PSA testing among PWH, the incidence of prostate cancer was similar by HIV status. These findings suggest that less screening contributed to lower observed incidence of prostate cancer in PWH.

COVID-19 Misinformation and Social Network Crowdfunding: Cross-sectional Study of Alternative Treatments and Antivaccine Mandates.

BACKGROUND: Crowdfunding is increasingly used to offset the financial burdens of illness and health care. In the era of the COVID-19 pandemic and associated infodemic, the role of crowdfunding to support controversial COVID-19 stances is unknown. OBJECTIVE: We sought to examine COVID-19-related crowdfunding focusing on the funding of alternative treatments not endorsed by major medical entities, including campaigns with an explicit antivaccine, antimask, or antihealth care stances. METHODS: We performed a cross-sectional analysis of GoFundMe campaigns for individuals requesting donations for COVID-19 relief. Campaigns were identified by key word and manual review to categorize campaigns into "Traditional treatments," "Alternative treatments," "Business-related," "Mandate," "First Response," and "General." For each campaign, we extracted basic narrative, engagement, and financial variables. Among those that were manually reviewed, the additional variables of "mandate type," "mandate stance," and presence of COVID-19 misinformation within the campaign narrative were also included. COVID-19 misinformation was defined as "false or misleading statements," where cited evidence could be provided to refute the claim. Descriptive statistics were used to characterize the study cohort. RESULTS: A total of 30,368 campaigns met the criteria for final analysis. After manual review, we identified 53 campaigns (0.17%) seeking funding for alternative medical treatment for COVID-19, including popularized treatments such as ivermectin (n=14, 26%), hydroxychloroquine (n=6, 11%), and vitamin D (n=4, 7.5%). Moreover, 23 (43%) of the 53 campaigns seeking support for alternative treatments contained COVID-19 misinformation. There were 80 campaigns that opposed mandating masks or vaccination, 48 (60%) of which contained COVID-19 misinformation. Alternative treatment campaigns had a lower median amount raised (US $1135) compared to traditional (US $2828) treatments (P<.001) and a lower median percentile of target achieved (11.9% vs 31.1%; P=.003). Campaigns for alternative treatments raised substantially lower amounts (US $115,000 vs US $52,715,000, respectively) and lower proportions of fundraising goals (2.1% vs 12.5%) for alternative versus conventional campaigns. The median goal for campaigns was significantly higher (US $25,000 vs US $10,000) for campaigns opposing mask or vaccine mandates relative to those in support of upholding mandates (P=.04). Campaigns seeking funding to lift mandates on health care workers reached US $622 (0.15%) out of a US $410,000 goal. CONCLUSIONS: A small minority of web-based crowdfunding campaigns for COVID-19 were directed at unproven COVID-19 treatments and support for campaigns aimed against masking or vaccine mandates. Approximately half (71/133, 53%) of these campaigns contained verifiably false or misleading information and had limited fundraising success.

Association of Negative Followup Biopsy and Reclassification during Active Surveillance of Prostate Cancer: A Systematic Review and Meta-Analysis.

PURPOSE: With the growing adoption of active surveillance clinical parameters that can tailor the intensity of monitoring are increasingly needed. Therefore, we aimed to evaluate the prognostic value of negative followup biopsy for reclassification and upgrading in prostate cancer patients managed with active surveillance. MATERIALS AND METHODS: The PubMed®, Web of ScienceTM, and Scopus® databases were queried to identify relevant studies published until November 2020 according to the Preferred Reporting Items for Systematic Review and Meta-analysis statement. We performed a formal meta-analysis for the reclassification and upgrading in the full cohort and selected subgroups. RESULTS: We identified 13 and 9 studies eligible for the systematic review and meta-analysis, respectively. A total of 2,628 patients were included in the meta-analysis. Any negative followup biopsy was associated with significantly lower risk of reclassification (HR 0.46, 95% CI 0.39-0.55; p <0.01), and upgrading (HR 0.54, 95% CI 0.44-0.66; p <0.01). For the confirmatory biopsy subgroup, the results remained significant for reclassification (HR 0.44, 95% CI 0.36-0.55; p <0.01) and upgrading (HR 0.55, 95% CI 0.42-0.73; p <0.01). These patterns remained robust among patients with only Gleason Grade prognostic group 1 (reclassification HR 0.47, 95% CI 0.39-0.57; p <0.01; upgrading HR 0.54, 95% CI 0.42-0.69; p <0.01). CONCLUSIONS: A negative followup biopsy is associated with an approximately 50% decrease in the risk of future reclassification and upgrading. Incorporation of the negative followup biopsy into current protocols should allow for personalized active surveillance tailoring and more precise decision making.

The Prognostic Association of Prostate MRI PI-RADS™ v2 Assessment Category and Risk of Biochemical Recurrence after Definitive Local Therapy for Prostate Cancer: A Systematic Review and Meta-Analysis.

PURPOSE: Although the Prostate Imaging-Reporting and Data System™ version 2 (PI-RADS™ v2) is a reliable diagnostic tool for significant prostate cancer, less is known about the prognostic significance of the structured reporting scheme for estimating oncologic outcomes after treatment. We aimed to synthesize the available evidence regarding the association of PI-RADS v2 score and risk of biochemical recurrence (BCR) among patients undergoing primary definitive treatment for prostate cancer. MATERIALS AND METHODS: We systematically queried the PubMed® and Web of Science™ databases to identify studies addressing the association between the PI-RADS v2 and treatment outcomes. We included studies through November 2020 that assessed the independent prognostic significance of PI-RADS v2. After assessing risk of bias and quality, we conducted a formal meta-analysis to estimate the pooled effects of prostate magnetic resonance imaging (MRI) classification on the risk of BCR. RESULTS: We identified 9 and 7 eligible studies including 2,274 and 1,215 patients for the systematic review and meta-analysis, respectively. Eight were conducted in the context of radical prostatectomy and 1 post-radiation. Among patients treated with radical prostatectomy, higher PI-RADS v2 scores were significantly associated with risk of BCR (pooled HR 3.06, 95% CI 2.16-4.33; p <0.01). There was no significant heterogeneity among studies. For all studies, PI-RADS v2 score remained significantly associated with BCR (pooled HR 3.19, 95% CI 2.28-4.45; p <0.01). CONCLUSIONS: Prostate MRI findings assessed with the PI-RADS v2 classification were independently associated with risk of BCR after definitive local therapy, primarily based on data from radical prostatectomy. These findings support the prognostic significance of MRI, in addition to its role in prostate cancer diagnosis.

Incidence, risk factors, and outcome of Clostridioides difficile infection following urological surgeries.

PURPOSE: To assess the incidence, risk factors, and clinical outcomes associated with (Clostridioides difficile infection) CDI following urological surgery, which is the leading cause of nosocomial diarrhea and a growing public health burden. METHODS: We queried the National Surgical Quality Improvement Program (NSQIP) to identify patients undergoing urological surgery in 2015-2016. We evaluated the 30-day incidence and factors associated with postoperative CDI and 30-day hospital readmission and length of stay as secondary outcomes. Among the subset of patients undergoing radical cystectomy with urinary diversion (surgery with highest CDI incidence) we used multivariable logistic regression analysis to evaluate independent clinical and demographic factors associated with postoperative CDI. RESULTS: We identified 98,463 patients during the study period. The overall 30-day incidence of CDI was 0.31%, but varied considerably across surgery type. The risk of CDI was greatest following radical cystectomy with urinary diversion (2.72%) compared to all other urologic procedures (0.19%) and was associated with increased risk of hospital readmission (p < 0.0001), re-operation (p < 0.0001), and longer mean length of stay (p < 0.0001) in this cohort. Among patients undergoing radical cystectomy with urinary diversion, multivariable logistic regression revealed that preoperative renal failure (OR: 5.30, 95% CI 1.13-24.9, p = 0.035) and blood loss requiring transfusion (OR: 1.67, 95% CI 1.15-2.44, p = 0.0075) were independently associated with CDI. CONCLUSIONS: In a nationally representative cohort, the incidence of CDI was low but varied substantially across surgery types. CDI was most common following radical cystectomy and associated with potentially modifiable factors such as blood transfusion and significantly longer length of stay.

National trends in the management of patients with positive surgical margins at radical prostatectomy.

PURPOSE: To evaluate practice patterns of planned post-operative radiation therapy (RT) among men with positive surgical margins (PSM) at radical prostatectomy. METHODS: We identified 43,806 men within the National Cancer Database with pathologic node-negative prostate cancer diagnosed in 2010 through 2014 with PSM. The primary endpoint was receipt of planned (RT) within a patient's initial course of treatment. We examined post-RP androgen deprivation therapy (ADT) with RT as a secondary endpoint. We evaluated patterns of post-operative management and characteristics associated with planned post-prostatectomy RT. RESULTS: Within 12 months of RP, 87.0% received no planned RT, 8.5% RT alone, 1.3% ADT alone, and 3.1% RT with ADT. In a multivariable logistic regression model, planned RT use was associated with clinical and pathologic characteristics as estimated by surgical Cancer of the Prostate Risk Assessment (CAPRA-S) category (intermediate versus low, OR = 2.87, 95% CI 2.19-3.75, P < 0.001; high versus low, OR = 10.23, 95% CI 7.79-13.43, P < 0.001), treatment at community versus academic centers (OR = 1.24, 95% CI 1.15-1.34, P < 0.001), shorter distance to a treatment facility (OR = 0.97 for each 10-mile, 95% CI 0.96-0.98, P < 0.001), and uninsured status (OR = 1.39, 95% CI 1.10-1.77, P = 0.005). The odds of receiving planned RT were lower in 2014 versus 2010 (OR = 0.76, 95% CI 0.68-0.85, P < 0.001). There was no significant change in the use of ADT with RT. High versus low CAPRA-S category was associated with the use of ADT in addition to RT (OR = 5.13, 95% CI 1.57-16.80, P = 0.007). CONCLUSION: The use of planned post-prostatectomy RT remained stable among patients with PSM and appears driven primarily by the presence of other adverse pathologic features.

Outcomes for urologic oncology procedures: are there differences between academic and community hospitals?

OBJECTIVE: To compare the rate of hospital-based outcomes including costs, 30-day readmission, mortality, and length of stay in patients who underwent major urologic oncologic procedures in academic and community hospitals. METHODS: We retrospectively reviewed the Vizient Database (Irving, Texas) from September 2014 to December 2017. Vizient includes ~ 97% of academic hospitals (AH) and more than 60 community hospitals (CH). Patients aged ≥ 18 with urologic malignancies who underwent surgical treatment were included. Chi square and Student t tests were used to compare categorical and continuous variables, respectively. RESULTS: We identified a total of 37,628 cases. There were 33,290 (88%) procedures performed in AH and 4330 (12%) in CH. These included prostatectomy (18,540), radical nephrectomy (rNx) 8059, partial nephrectomy (pNx) (5287), radical cystectomy (4421), radical nephroureterectomy (rNu) (1006), and partial cystectomy (321). There were no significant differences in 30-day readmission rates or mortality for any procedure between academic and community hospitals (Table 1), p > 0.05 for all. Length of stay was significantly lower for radical cystectomy and prostatectomy in AH (p < 0.01 for both) and lower for rNx in CH (p = 0.03). The mean direct cost for index admission was significantly higher in AH for rNx, pNx, rNu, and prostatectomy. Case mix index was similar between the community and academic hospitals. CONCLUSION: Despite academic and community hospitals having similar case complexity, direct costs were lower in community hospitals without an associated increase in readmission rates or deaths. Length of stay was shorter for cystectomy in academic centers.

Association of prescription opioids and incident cardiovascular risk factors among post-9/11 Veterans.

Reports indicate that long-term opioid therapy is associated with cardiovascular disease (CVD). Using VA electronic health record data, we measured the impact of opioid use on the incidence of modifiable CVD risk factors. We included Veterans whose encounter was between October 2001 to November 2014. We identified Veterans without CVD risk factors during our baseline period, defined as the date of first primary care visit plus 365 days. The main exposure was opioid prescriptions (yes/no, long-term (i.e. ≥90 days) vs no opioid, and long-term vs short-term (i.e. <90 days)), which was time-updated yearly from the end of the baseline period to February 2015. The main outcome measures were incident CVD risk factors (hypertension, dyslipidemia, diabetes, obesity, and current smoking). After excluding prevalent CVD risk factors, we identified 308,015 Veterans. During the first year of observation, 12,725 (4.1%) Veterans were prescribed opioids, including 2028 (0.6%) with long-term exposure. Compared to patients without opioid use, Veterans with opioid use were more likely to have CVD risk factors. Those with long-term exposure were at higher risk of having hypertension (adjusted average hazards ratio [HR] 1.45, 99% confidence interval [CI] 1.33-1.59), dyslipidemia (HR 1.45, 99% CI 1.35-156), diabetes (HR 1.30, 99% CI 1.07-1.57), current smoking status (HR 1.34, 99% CI 1.24-1.46), and obesity (HR 1.22, 99% CI 1.12-1.32). Compared to short-term exposure, long-term had higher risk of current smoking status (HR 1.12, 99% CI 1.01-1.24). These findings suggest potential benefit to screening and surveillance of CVD risk factors for patients prescribed opioids, especially long-term opioid therapy.

Redefining the Role of Surgical Management of Metastatic Renal Cell Carcinoma.

PURPOSE OF REVIEW: The treatment landscape for metastatic renal cell carcinoma (mRCC) continues to evolve with ongoing advancements in systemic therapy, raising further questions about the optimal role of surgery in the management of mRCC. Herein, we provide a context and review of the recent evidence concerning the role of surgical therapy for patients with mRCC including cytoreductive nephrectomy and distant metastatectomy. RECENT FINDINGS: One randomized trial has been published in the targeted therapy era suggesting that initial systemic therapy is non-inferior to cytoreductive nephrectomy among patients with intermediate and poor-risk mRCC. Delaying cytoreductive nephrectomy until after systemic therapy may be a viable treatment approach, although a high level of evidence is lacking. Additional questions remain regarding the sequence of surgery with systemic therapy, utility of distant metastatectomy, as well as the application of these findings to the current generation of immunotherapy. Recent evidence challenges the need of upfront cytoreductive nephrectomy for unselected patients with mRCC. However, surgical therapy continues to play an important role in the management of the disease.

Genetic testing for hereditary prostate cancer: Current status and limitations.

A significant proportion of prostate cancer diagnoses may be associated with a strong hereditary component. Men who have multiple single-gene polymorphisms and a family history of prostate cancer have a significantly greater risk of developing prostate cancer. Numerous single-gene alterations have been confirmed to increase the risk of prostate cancer. These include breast cancer genes 1 and 2 (BRCA1 and BRCA2, respectively), mutL homolog 1 (MLH1), mutS homologs 2 and 6 (MSH2 and MSH6, respectively), postmeiotic segregation increased 2 (PMS2), homeobox B13 (HOXB13), checkpoint kinase 2 (CHEK2), nibrin (NBN), BRCA1-interacting protein C-terminal helicase 1 (BRIP1), and ataxia telangiectasia mutated (ATM). Currently, there are no uniform guidelines on the definition of hereditary prostate cancer and genetic testing. With the advent of next-generation sequencing, which is capable of testing multiple genes simultaneously, and the approval of olaparib for BRCA1/BRCA2 or ATM-mutated, metastatic, castrate-resistant prostate cancer, it is being recognized that the results of genetic testing have an impact on therapeutic strategies. In this review, the authors examine the role of genetic counseling and testing, the challenges of insurance coverage for testing, the available germline and somatic testing panels, and the complexity of each testing method and its implications.

Survival outcomes for patients with localised upper tract urothelial carcinoma managed with non-definitive treatment.

OBJECTIVE: To investigate the outcomes of patients with upper tract urothelial carcinoma (UTUC) with non-definitive therapy, which currently remains unknown. PATIENTS AND METHODS: We used the Surveillance, Epidemiology, and End Results (SEER) database to identify individuals with a localised, histologically confirmed kidney/renal pelvis and ureteric UC. Survival analysis using the Kaplan-Meier method was performed. A competing risk model evaluated the cumulative incidence and predictors of cancer-specific mortality (CSM). RESULTS: We identified 633 (7.6%) individuals who did not receive surgery. These individuals were significantly older (median age 81 vs 71 years, P < 0.001) than surgically managed patients. The median overall survival (OS) was significantly shorter compared to the surgical cohort (1.9 vs 7.8 years, P < 0.001). The 3-year disease-specific survival (DSS) for patients without surgery was significantly lower compared to those with surgery, at 73.7% vs 92.4%, respectively (P < 0.001). The 3-year DSS for patients with high-grade tumours was worse when compared to patients with low-grade tumours, at 65.1% vs 82.9%, respectively (P < 0.001). The 3-year cumulative CSM was 26.3%. On multivariable analysis, older age (hazard ratio [HR] 1.05, P < 0.001) and high tumour grade (HR 1.88, P < 0.001) were predictors of worse outcomes. CONCLUSIONS: In this population-based cohort, 7.6% of patients with UTUC were managed with a non-definitive approach. The median OS for the untreated cohort was significantly shorter compared to the surgical cohort (1.9 vs 7.8 years, respectively). These data may be helpful in counselling patients who are poor surgical candidates, as non-definitive therapy may provide reasonable oncological outcomes.

Variation in National Opioid Prescribing Patterns Following Surgery for Kidney Stones.

Background: Opioid misuse is a significant public health problem. As initial exposures to opioids are frequently encountered through the management of postoperative pain, we examined patterns of opioid prescribing following surgical treatment for nephrolithiasis. Methods: We identified patients with nephrolithiasis in the national Women Veterans Cohort Study (WVCS) who were treated surgically by diagnosis and procedure codes. Using standard conversion factors, we calculated the morphine milligram equivalent (MME) dose prescribed. We used descriptive statistics to characterize opioid prescription across management strategy and multivariable regression to examine clinical and demographic characteristics associated with dispensed dose. Results: We identified 22,609 patients diagnosed with kidney stones during 1999-2014, 1,976 of whom were treated surgically and 1,582 (80.1%) of whom received an opioid prescription. The median age was 39 years, and 1,366 (90%) were male; 1,314 (86.3%) were treated with ureteroscopy, 172 (11.3%) with extracorporeal shockwave lithotripsy, and 36 (2.4%) with percutaneous nephrolithotomy. The median number of days supplied per opioid prescription (interquartile range) was 10 (5-14), and patients were dispensed a median of 180 (140-300) MME. A total of 6.4% of patients received ≥50 MME/d. On multivariable analysis, comorbid diagnosis of post-traumatic stress disorder (PTSD) was associated with higher total dispensed dose, whereas surgery type was not. Conclusions: We observed substantial variation in opioid prescribing following surgical treatment of nephrolithiasis. Although type of surgical intervention did not impact opioid dosing, patients with a diagnosis of PTSD were more likely to receive higher doses. This work can inform efforts to improve the safety and efficacy of postoperative opioid prescribing.
